IMPROVEMENT IN GRAIN-DRILLS.

Specification forming part of Letters Patent No. 40,495, dated November 3, 1863.

To all whom it may concern.-

Be it known that we, H. B. MYERS and G. A. MYERS, of Schoolcral't, in the county of Kalamazoo and State of Michigan, have invented a new and Improved Seeding-Machine; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, making a part of this specification, in which Figure 1 is a side sectional view of our invention, taken in the line a: m, Fig. 2; Fig. 2, a plan or top view of the same; Fig. 3, a back view of a portion of the same; Fig. 4, a detached vertical section of a hopper pertaining to the invention.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents an axle, on the ends of wh ch there are placed wheels B B; and 0 is a rectangular frame, which is framed into the front side of the axle, and has a draft-pole, D, secured centrally to it. The frame 0 has a bar, a, in it parallel withthe axle A and at such a distance from it as to form a space or socket between it and the axle to receive a bar at the bottom of a seed-box, E, and serve to support the latter firmly in position and still admit of its being readily removed when necessary. The bottom of the seed-box E is formed of a slide, F, perforated with holes I) c. This slide is equal in width to the lower part of the seed-box E, and the latter is divided into two longitudinal parts by a vertical central partition, d. The front compartment of the seedbox is divided into a series of small compartments by means of transverse vertical partitions 6, the lower ends of which serve as cutoffs, and the slide F has a spiral spring,f, fitted in it, which spring has a tendency to keep the holes I), which are in the front part of the seedbox, from underneath the partition 6, and to keep the slide F against a cam, G or K, at the inner side of the wheel B or B. In the back part of the seed-box E there are placed three corn-hoppers, g gg, in which the holes a of the slide F work, and to the slide F there is attached a hand-lever, H,by which the slide may be rendered inoperative at any time. The cam G and the springfgive a reciprocating motion to the slide F and cause the seed to be discharged from the compartments in the front part of the seed-box through holes h in the bar D, on which the seed-box rests, the seed being discharged when the holes b are underneath the partition e and in line with the holes h in the bar D. In the back part of the bar D the upper ends ofdrill-teeth l are fitted. Three of these teeth are tubular those which are in line with openings t in the bar D-through which seed is discharged from the hoppers g g g. The other two drill-teeth are attached to the back of a box, J, which is placed underneath the front part of the seed-box E. The upper ends of the drill-teeth are cut in dovetail form, as shown at J in Fig. 3, and said dovetail parts fit in dovetail recesses made in the back part of bar D.; The drill-teeth, therefore, it will be seen, which are attached to box J, secure said box to the seed-box E, and said parts may be readily detached, when necessary, by simply raising the seed-box out from the framing.

When the hoppers G are used the implement will plant in hillsand three rows at a time, the corn being placed in the hoppers and the slide F actuated by the cam K on the wheel B.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The semicircular lever 0, applied to the seed-box E, as shown, when said seed-box is arranged or fitted in the frame 0, as and for the purpose specified.

2. The drill-teeth I, provided with dovetails j on their upper ends to fit in corresponding recesses in the back of the bar D, to secure the box J to the seed-box E, as set forth.
